Is it possible to Toggle Focus?

[timii]

Hi,

I'm currently using :NvimTreeFocus to focus the file explorer when editing a file, but I can't toggle the focus back to the current file without selecting a file from the file explorer.

My question now is, if it's possible to toggle the focus between the current file and file explorer, without selecting a file in the file explorer, or not? And if it's possible, how can I do it?

I'm sorry if the same question has been answered already, but I couldn't find an answer yet.

If any other information is needed, I will gladly try to provide as much as I can.

Any help is greatly appreciated, thanks.

You can use wincmd p within nvim-tree to switch back to previous window. But after quick test I couldn't get it to work (always switching to the next window on the right instead of previous one).

@alex-courtis should that work:

{ key = 'some-key', action_cb = function() vim.cmd.wincmd 'p' end }

? It works fine executed from command line.

Interesting, thanks for your response. Does your provided snippet result in a different behavior or any advantages, or does it not matter which one to use?

The first one is a side effect that will break once you upgrade to c4ac723

The second will move to the previous window, rather than the window of the file under the cursor.

I ended up with single 'standalone' mapping:

vim.keymap.set('n', '<leader>f', function()
  if vim.fn.bufname():match 'NvimTree_' then
    vim.cmd.wincmd 'p'
  else
    nvimtree.find_file(true)
  end
end, { desc = 'nvim-tree: toggle' })

vim.keymap.set via on_attach is the desired end state and works well today.

The full implementation with all the conveniences is still a work in progress. #1579

@timii, you can try this:

function toggle_nvimtree()
	if vim.fn.bufname():match 'NvimTree_' then
		vim.cmd.wincmd 'p'
	else
		vim.cmd('NvimTreeFindFile')
	end
end
